by binlogging some SET ONE_SHOT CHARACTER_SETetc,
which will be enough until we have it more compact and more complete in 5.0. With the present patch,
replication will work ok between 4.1.3 master and slaves, as long as:
- master and slave have the same GLOBAL.COLLATION_SERVER
- COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
- application does not use the fact that table is created with charset of the USEd db (BUG#2326).
all of which are not too hard to fulfill.
ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
so we give error if used for non-charset vars.
Fix for BUG#3875 "mysqlbinlog produces wrong ouput if query uses
variables containing quotes" and BUG#3943 "Queries with non-ASCII literals are not replicated
properly after SET NAMES".
Detecting that master and slave have different global charsets or server ids.
mysql-test/r/rpl_server_id1.result:
it's normal to not run as I have added a test to compare server ids of master and slave
at startup and stop if equal (unless --replicate-same-server-id)
mysql-test/r/rpl_user_variables.result:
result update (as we now print charset of user var).
mysql-test/r/user_var.result:
result update
mysql-test/t/rpl_server_id1.test:
no need to select as slave is not running
mysql-test/t/user_var.test:
testing if the content of user vars is escaped when mysqlbinlog prints them,
and if the name is backquoted.
sql/lex.h:
new keyword ONE_SHOT
sql/log.cc:
when writing to the binlog, before writing the actual statement, write some SET ONE_SHOT CHARACTER_SET_CLIENT etc
for the slave to know the charset variables (which are important as they affect the inserted data).
sql/log_event.cc:
print charset and collation of user var in mysqlbinlog and SHOW BINLOG EVENTS.
escape the content of the var. Backquote its name.
Will ask Bar to check that using my_charset_bin for escaping is ok.
sql/set_var.cc:
understand SET CHARACTER_SET_CLIENT=10 (don't require a string, accept a number).
Refuse changing of GLOBAL CHARACTER_SET_SERVER/COLLATION_SERVER if binlog or slave,
as it will make the master or slave make wrong assumptions.
A function to catch SET ONE_SHOT on non-charset variables (which is forbidden)
sql/set_var.h:

sql/slave.cc:
when I/O slave thread starts, verify that master's and slave charsets match.
And by the way verify that server ids are different.
Don't fail if UNIX_TIMESTAMP() can't be done on master (very old master), that's

The code in mysql_create_table() code assumes that if lower_case_names==2 then table alias
should contain unchanged table name, and this was not true for temporary tables which
had 'tmp-table' constant as alias. Now we are using table name as alias for such tables.
sql/sql_lex.cc:
Removed tmp_table_alias constant which is no longer used.
sql/sql_lex.h:
Removed tmp_table_alias constant which is no longer used.
sql/sql_yacc.yy:
Let us use table name instead of 'tmp-table' as alias for table being created by
CREATE TEMPORARY TABLE statement. This fixes failing temp_table.test on Darwin 7.3
since mysql_create_table() code assumes that if lower_case_names==2 then table alias
should contain unchanged table name (and now this assumtion is true but it were false
for temporary tables before...).

Fix for ORDER BY handling in GROUP_CONCAT()
Final version of patch.
Adds support for specifying of DEFAULT NOW() and/or ON UPDATE NOW()
clauses for TIMESTAMP field definition.
Current implementation allows only one such field per table and
uses several unireg types for storing info about this properties of
field. It should be replaced with better implementation when new
.frm format is introduced.
include/mysqld_error.h:
Added error codes for case when we have more than one column with NOW()
in DEFAULT or ON UPDATE clauses and for case when we are using ON UPDATE
clause with wrong type.
mysql-test/r/create.result:
Added tests for using of DEFAULT NOW() and ON UPDATE NOW() with
non-TIMESTAMP fields.
mysql-test/r/show_check.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW CREATE TABLE.
mysql-test/r/system_mysql_db.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW CREATE TABLE.
mysql-test/r/type_ranges.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW COLUMNS.
mysql-test/r/type_timestamp.result:
Added tests for various DEFAULT and ON UPDATE clauses for TIMESTAMP
fields definitions.
mysql-test/t/create.test:
Added tests for using of DEFAULT NOW() and ON UPDATE NOW() with
non-TIMESTAMP fields.
mysql-test/t/type_timestamp.test:
Added tests for various DEFAULT and ON UPDATE clauses for TIMESTAMP
fields definitions.
sql/field.cc:
Added support for various combinations of DEFAULT and ON UPDATE clauses
for TIMESTAMP field.
Setting TABLE::timestamp* members for TIMESTAMP fields with auto-set
option taking into account their unireg type (which corresponds to
various DEFAULT/ON UPDATE values combinations). Replaced
TABLE::time_stamp with TABLE::timestamp_default_now/on_update_now
couple moved their setup to separate method set_timestamp_offsets(),
which now is called from open_table instead of Field_timestamp cons.
sql/field.h:
Added more unireg types for handling of DEFAULT NOW() and ON UPDATE
NOW() for TIMESTAMP fields.
Fixed value corresponding to DEFAULT item for TIMESTAMP field.
sql/ha_berkeley.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_heap.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_innodb.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_isam.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_isammrg.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_myisam.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_myisammrg.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/item_func.h:
We need to distinguish NOW() from other function for using in
DEFAULT and in ON UPDATE clauses.
sql/item_timefunc.h:
We need to distinguish NOW() from other function for using in
DEFAULT and in ON UPDATE clauses.
sql/mysql_priv.h:
Added parameter for ON UPDATE value to add_field_to_list() function.
sql/share/czech/errmsg.txt:

sql/sql_base.cc:
Added setup of TABLE::timestamp_default_now/on_update_now pair
for each statement to open_table().
sql/sql_insert.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. Added check for case then REPLACE could not
be converted to UPDATE because of different DEFAULT/ON UPDATE values
for TIMESTAMP field.
sql/sql_lex.h:
Added member for value used in ON UPDATE clause to st_lex.
sql/sql_load.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. We don't need to restore these members
since they are set up for each statement in open_table().
sql/sql_parse.cc:
Added handling of DEFAULT NOW() and ON UPDATE NOW() clauses for
TIMESTAMP fields to add_field_to_list() function.
sql/sql_show.cc:
Added support for DEFAULT CURRENT_TIMESTAMP (aka NOW() ) and
ON UPDATE CURRENT_TIMESTAMP to SHOW CREATE TABLE and SHOW COLUMNS.
sql/sql_table.cc:
mysql_create_table() function - added check for number of TIMESTAMP
fields with auto-set values and replacing of old style TIMESTAMPs
with their newer analogs.
mysql_alter_table(): Using TABLE::timestamp_default_now/on_update_now
pair instead of old TABLE::time_stamp. We don't need to restore these
members since they are set up for each statement in open_table().
sql/sql_update.cc:
Left only setting of TABLE::timestamp_default_now/on_update_now
to 0 since they should be already set up in open_table().
sql/sql_yacc.yy:
Added support for DEFAULT NOW() and ON UPDATE NOW() in field
definitions.
sql/table.h:
Replaced TABLE::time_stamp withTABLE::timestamp_default_now/timestamp_on_update_now
pair which allows to distinguish TIMESTAMP's with various DEFAULT/ON UPDATE
clauses and optimize checks if TIMESTAMP field should be set to NOW()
in handlers.
sql/unireg.cc:
Now we are marking only TIMESTAMP fields with NOW() as default or
as on update value as special field for unireg.
This is to enable table handlers to implement online create/drop index.
It consists of some parts:
- New default handler methods in handler.h
- Split of mysql_alter_table. It decides if only one kind of
alteration is to be done (e.g. only create indexes or only drop
indexes etc.) It then calls the specialized new handler method if
the handler implements it. Otherwise it calls real_alter_table.
- The parser sets flags for each alter operation detected in a
command. These are used by mysql_alter_table for the decision.
- mysql_prepare_table is pulled out of mysql_create_table. This is
also used by mysql_create_index to prepare the key structure array
for the handler. It is also used by mysql_create_index and
mysql_drop_index to prepare a call to mysql_create_frm.
- mysql_create_frm is pulled out of rea_create_table for use by
mysql_create_index and mysql_drop_index after the index is
created/dropped.
Thanks to Antony who supplied most of the changes.
sql/handler.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New virtual handler methods with default implementation and return flags.
sql/mysql_priv.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New function prototypes. mysql_prepare_table is pulled out of
mysql_create_table. It prepares a table structure, which is used by
mysql_create_table, mysql_create_index and mysql_drop_index.
real_alter_table is pulled out of mysql_alter_table. The latter only
looks if the requested operation can be done by specialized functions
or else calls real_alter_table, which does the real thing.
mysql_add_column and mysql_drop_colunm are for future use. They simply
call real_alter_table. mysql_create_frm is pulled out of
rea_create_table. It is called also from mysql_create_index and
mysql_drop_index after successful create/drop index.
mysql_alter_table prototype is extended by the new alter_flags argument.
sql/sql_base.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_index and mysql_drop_index moved to sql_table.cc.
sql/sql_lex.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Definitions for the new alter_flags.
sql/sql_parse.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Extend the calls to mysql_alter_table by the new alter_flags argument.
sql/sql_table.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_prepare_table is pulled out of mysql_create_table.
mysql_create_index and mysql_drop_index are changed so that they use
the new handler functions if the handler implements them.
mysql_add_column and mysql_drop_column are for future use. They simply
call real_alter_table. mysql_alter_table only decides which function
to use for the requested operation. real_alter_table implements most
of what mysql_alter_table did before.
sql/sql_yacc.yy:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Set the alter_flags where appropriate.
sql/unireg.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_frm is pulled out of rea_create_table.
reviewed in Saint-Petersbourg (including post-review fixes).
include/my_sys.h:
Added clear_alloc_root (reset alloc root without freeing its memory)
sql/item.h:
- rename setup_param -> set_parap (function assigns parameter value to item)
sql/mysql_priv.h:
- all return values are void, because return value is never checked in
dispatch_command
- removed unused declaration of setup_param_functions
sql/protocol.h:
- unused declarations of setup_params_data* removed
sql/sql_class.cc:
Cleanup:
- bzero(mem_root) replaced with clear_alloc_root
- query_id and command members moved back to THD from Statement
Assignment of mem_root, free_list, query_id and command optimized
away from set_statement().
sql/sql_class.h:
- query_id and command moved back to THD from Statement
sql/sql_lex.h:
- better type for param_list
- param_count is the same thing as param_list.elements
sql/sql_parse.cc:
- comments for dispatch_command
sql/sql_prepare.cc:
Cleanup:
- added comments to many functions and removed trailing spaces in many
lines, some stale comments removed.
- it's faster to iterate using pointers, than classes
- Renames: error_in_prepare renamed to get_longdata_error (because it is set
when there is an error in mysql_send_longdata, rather than in
mysql_prepare), embedded versions of placeholder assignement functions
now have prefix emb_, setup_ functions renamed to set_, because they
perform assignment, not installation, setup_params_data now doesn't
call insert_params and was renamed to setup_set_param_functions,
- find_prepared_statement should not send error if called from no-reply
calls, like mysql_stmt_reset
- error reporting is checked up, to always report errors and not report
errors twice. send_prep_stmt can be done mostly in send_prepare_result,
rather than in test_* functions.
- now we don't need to reinit THD->mem_root/free_list in mysql_stmt_execute,
because it's not reset there.
